Ascidia prunum

Local name: plommonsjöpung

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Ascidia prunum faces significant pressure from coastal development and marine pollution in its shallow water habitats. Ocean acidification poses an emerging threat to this filter-feeding tunicate, as changing pH levels can affect its calcium carbonate structures and feeding efficiency. Bottom trawling and dredging activities in coastal waters directly damage the seafloor communities where this species anchors and feeds.

Threat summary

Habitat

This marine tunicate inhabits shallow coastal waters, typically attaching to hard substrates such as rocks, shells, and artificial structures in the subtidal zone. It is commonly found in areas with moderate water flow that supports its filter-feeding lifestyle, often in depths ranging from a few meters to approximately 50 meters.
